Why does the code do this i.e. xor-ing the eap ID etc. with bytes 3,4,5
of "State"? I'm sure there's a good reason, but I can't figure out what
it is.
Help with debugging weird issues.  If the EAP ID is "hidden" in the
State attribute, we can decode it in later transactions.  A misbehaving
client will send the wrong State, and we'll be able to figure out which
transaction it came from.
